Currently there is no share parameters between launch configurations or to change several parameters at once. The idea is to let the user define Launch Configuration Templates that behave like cookie cutters. A configuration can be based on a template, which seeds attributes in the configuration with the settings specified in the template. Once a configuration has been created, the user can override any initial settings from the template. The user can also modify the template and push changes out to the configurations based on it. A configuration maintains a backpointer to its template, but is a complete standalone configuration than can be launched, exported, shared, etc.
